What Genetic Stripe looks like

Clean dorsal stripe

Pattern mutation that converts the normal ball python blotch pattern into a pair of continuous dorsal stripes running the length of the body. Normal ball python coloration is retained but the pattern is completely reorganized. Het Genetic Stripe animals appear normal with no reliable visual markers for carrier status.

How to identify it: Two continuous dorsal stripes from head to tail. Normal coloration (browns, blacks, golds) but in a completely different pattern layout. No lateral blotching. Clean sides between the stripes and the belly.

How Genetic Stripe is inherited

Genetic Stripe follows a recessive inheritance pattern, carried on the Genetic Stripe allele (locus GStripe).

What does het genetic stripe mean?

Because Genetic Stripe is recessive, an animal needs two copies of the allele to show the trait visually. An animal with a single copy is called het genetic stripe (heterozygous). A het animal looks normal but carries the gene, so pairing two het genetic stripe animals produces, on average, one in four visual genetic stripe offspring.
